This invention pertains to shower devices for bath fixtures and the like, and more particularly to a head plate for incorporation in a shower head of any of the usual types.

The ordinary shower head plates are usually made either with teats rojecting from the exterior surface thereof, t at is, the surface from which the water emerges, in which case it is diflicult, if not impossible, to

finish the surface so as to present an attractive appearance, or, with plane, flat interior and exterior surfaces, in which case unless the thickness of the shower head plate be of undesirable and unusual thickness, water issuing from the holes or orifices therethrough cannot be directed properly and may go in any direction. Also, in either case, the interior flat face permits sediment and debris to be carried more or lessdirectly to the orifices or holes therethrou h and to clog them. These and other ob ectionable features are entirely obviated or minimized by my invention.

With the invention, the exterior face of the water will issue in streams of predetermined directions. By reason of the teats or projections on the interior face of the shower head plate, the plate is made self-cleaning, for water impinging against the interior surfaces of the plate between the teats will swirl thereagainst and return for a short distance generally in the direction from which it came in so doing, sweep past and over the interior ends of the orifices or openings and carry away any dbris and sediment which might lodge or tend to lodge about or over the mouths of the orifices.

Such are a few of the more important ob- 1888. Serial Io. man.

jects and accomplishmentsof the invention, and these and others will or should appear and be more clearly understood from the following description and claims, and from the drawing, in which,

Fig. 1 is a longitudinal sectional view of one type of shower head including the body and head plate with my invention applied thereto, I

Fig. 2 is a similar view of a modified type of shower head, and

Fig. 3 is a plan view of the outer face of the shower head illustrated in Fig. 2.

The shower head illustrated in Fig. 1 comprises a hollow body 2 more or less of hell shape the apex of which may be threadedly or otherwise connected with a water su ply ipe 3. The lower or outer end of the libdy is provided with a thickened flange portion 4 which may be internally threaded, as shown at 5, for threaded engagement with a similarly threaded flange 6 on a head plate 7. The plate 7 may be cast or otherwise formed,

ut, however made, is provided with any desirable number of independent teats or projections 8 preferably of the same height on its interior surface generally designated 9. The teats are also preferably formed with their outer walls converging toward their in nor ends. Each teat and the plate thereat is drilled longitudinally to provide a water passage 10 leading from the interior head to the exterior surface 11 of the plate and these passa es are of such length as to impart a more ess definite direction of fiow under any reasonable water supply pressure.

When water entering the head from the ipe 3 impinges against the interior surface 9 etween the projections or teats 8 it swirls or is deflected backwardly along the walls of the projections and appears to eddy or swirl about and across the free ends of the teats and about and cross'the inner ends of the water passages 10. This action and whatever other eddying and swirling of the water takes place, has the effect of dislodging and breaking up any deposits of sediment and debris which might clog or tend to clog the water passages 10. Furthermore, the eddying currents of water, whether the head be entirely j as filled or not, will tend to prevent the accumulation of sedimentary and other dbris de- 'posits on the inner face of the head plate and will turn and twist and break the particles of dbris and sediment entering the head until they are small enough or so positioned that they will readily pass through the small water assages.

In igs. 2 and 3, the pipe 3 is shown as emptying into a shower head body 12 of sli htly difi'erent type than that illustrated in ig. 1. In this type of shower head the head plate 13 has a circumferential flange 14 about which the large end of the body is spun 1 or rolled, as shown at 15, with a gasket 16 interposed between the rolled edge or end portion of the body and the interior surface 17 of the plate. In this special form of head plate the teats 18 are drilled, as in the previous instance, to provide water passages 19 which are of a larger size than the water passages 10, and a central passage 20 of a still larger size. In this form also, three equally spaced strengthening ribs 21 are 25 formed integral with the interior surface of the plate 13 and the water passages are drilled therethrough. Although no special individual bosses surround the inner ends of these passages, the ribs 21 serve the same purpose. The operation of this form of the invention is substantially identical with that of the form prior described.

It should now be clear that I not only attain all of the objects above set forth with their attendant advantages, but that the invention is susceptible of wide modification and variation from the forms illustrated and described. I do not, therefore, desire to be limited by the embodiments of the invention illustrated and described, but only by the spirit of the invention and the scope ofthe appended claims.

I claim:

1. In a shower head, a plate having a plurallty of teats secured to and projecting from its inner surface, each of said teats and said plate having water passages therethrough, and the outer walls of said teats converging toward their inner ends.

2. In a shower head, a head plate having a plurality of integral teats projecting upwardly from its inner surface, said plate having water passages of substantially uniform diameter extending from its exterior surface to the interior of the head through portions of said teats, the outer walls of said teats converging toward their inner ends.

3. In a shower head, a hollow body open at one end, a head plate for closing said open in inwar ly projecting teats. and means inend of said body, means connected with said 1,7o2,eas

terior of said body for causing water impinging against said plate to sweep dbris away from the inner mouths of said'passages.

4. In a shower head, a hollow body member open at one end, a head plate connected to said member over said opening for closing the same, said plate having a plurality of water passages t erethrough from its interior to its exterior sides, means for supplying water to the interior of said member and substantially directly against the interior side of said plate, and means for causing water impinging on the interior surface of said plate between said assages to be deflected across the margins 0 the interior ends of said passages in a direction other than that of water flowing out of said head through said passages.

In witness of the foregoing I afiix my sig nature.
